The acquisition section acquires a proximity coordinate when a proximity operation is made on a touch panel first, and then acquires a contact coordinate when a contact operation is made thereon. When the proximity coordinate and the contact coordinate are different from each other, the determination section determines whether or not the acceleration of the portable terminal which is obtained based on the acceleration of the portable terminal from a point, when the proximity coordinate is acquired to a point when the contact coordinate is acquired, is made in a predetermined direction with respect to a movement direction from the proximity coordinate to the contact coordinate. When the acceleration of the portable terminal body is made in the predetermined direction, the determination section 31E determines the proximity coordinate as the operation coordinate.SELECTED DRAWING: Figure 2

Description

  The present invention relates to an electronic device and a coordinate determination program.

  In recent years, for example, electronic devices such as tablet terminals and smartphones have a hovering function that detects a non-contact operation, that is, a proximity operation without touching an operation finger on a touch panel screen. The electronic device uses, for example, a hovering function, acquires proximity coordinates when a proximity operation is detected on the touch panel screen, determines the acquired proximity coordinates as operation coordinates, and executes a command corresponding to the proximity coordinates. In addition, the electronic device may acquire the contact coordinates at the time when the touch operation is detected on the touch panel screen after acquiring the close coordinates at the time when the touch operation is detected on the touch panel screen. Then, the electronic device determines the acquired contact coordinates as operation coordinates, and executes a command corresponding to the contact coordinates.

  Furthermore, when the electronic device shakes between the proximity coordinate acquisition at the time of the proximity operation and the contact coordinate acquisition at the time of the contact operation, the electronic device determines that the contact operation due to the shake occurs regardless of the magnitude of the shake. A technique is also known in which proximity coordinates before contact operation detection is handled as operation coordinates.

JP2011-257899A

  However, in the electronic device, for example, even when the electronic device body shakes very little between the acquisition of the proximity coordinate and the acquisition of the contact coordinate, the proximity coordinate is handled as the operation coordinate. In other words, the electronic device treats the proximity coordinates before detecting the contact operation as the operation coordinates when the electronic device main body shakes immediately before the contact operation even though the user intentionally performed the contact operation. Therefore, it becomes a factor of erroneous input.

  In one aspect, an object of the present invention is to provide an electronic device and a coordinate determination program that can select an operation coordinate intended by a user even when a movement of the electronic device not intended by the user occurs immediately before the touch operation.

  In one mode, it has an acquisition part, a judgment part, and a determination part. An acquisition part acquires the contact coordinate at the time of contact operation, after acquiring the proximity coordinate at the time of proximity operation on a touch panel. When the proximity coordinate and the contact coordinate are different, the determination unit determines that the acceleration direction of the electronic device obtained from the acceleration of the electronic device body from the proximity coordinate acquisition to the contact coordinate acquisition is from the proximity coordinate to the contact coordinate. It is determined whether the direction is a predetermined direction with respect to the moving direction. The determining unit determines the proximity coordinate as the operation coordinate for executing the operation command when the acceleration direction of the electronic device main body is the predetermined direction.

  As one aspect, even when the movement of the electronic device unintended by the user occurs immediately before the touch operation, the operation coordinates intended by the user can be selected.

  Hereinafter, embodiments of an electronic device and a coordinate determination program disclosed in the present application will be described in detail based on the drawings. The disclosed technology is not limited by the present embodiment. Moreover, you may combine suitably the Example shown below in the range which does not cause contradiction.

  FIG. 1 is an explanatory diagram illustrating an example of the mobile terminal 1 according to the present embodiment. The mobile terminal 1 shown in FIG. 1 is an electronic device such as a tablet terminal or a smartphone. The mobile terminal 1 includes a speaker 11, a microphone 12, an LCD (Liquid Crystal Display) 13, a touch panel 14, a camera 15, Bluetooth 16, and a GPS (Global Positioning System) 17. The portable terminal 1 includes a wireless unit 18, a wireless local area network (WLAN) wireless unit 19, a communication CPU (Central Processing Unit) 20, an ISP (Imaging Signal Processor) 21, an audio DSP (Digital Signal Processor) 22, Have Further, the mobile terminal 1 includes a vibration unit 23, a geomagnetic sensor 24, an acceleration sensor 25, a gyro sensor 26, a capacitance sensor 27, and a sub processor 28. Furthermore, the mobile terminal 1 includes a nonvolatile memory 29, a RAM (Random Access Memory) 30, and an application CPU 31.

  The speaker 11 and the microphone 12 are interfaces that input and output audio, for example. The LCD 13 is an output interface that displays various information on the screen. The touch panel 14 is an input interface for inputting a touch operation on the screen of the LCD 13. The camera 15 has an imaging function for obtaining a still image or a moving image, for example. The Bluetooth 16 is an interface that manages a short-range wireless communication function. The GPS 17 is a system that measures the current position of the mobile terminal 1 itself using a GPS satellite.

  The wireless unit 18 is an interface that controls a normal long-distance wireless function. The WLAN radio unit 19 is an interface that controls the WLAN function. The communication CPU 20 is a CPU that controls various communication functions. The ISP 21 is a processor that controls image signal processing. The audio DSP 22 is a processor that controls audio signal processing. The vibration unit 23 is a vibration function that vibrates at a set cycle according to a signal such as an incoming signal, for example, in order to notify the user of an incoming mail or voice call.

  The sub processor 28 is an external processor. The geomagnetic sensor 24 is, for example, a sensor that detects the orientation of the mobile terminal 1. The acceleration sensor 25 is a sensor that detects acceleration in a predetermined axial direction of the mobile terminal 1 itself, for example, three axial directions of the x axis, the y axis, and the z axis. The gyro sensor 26 is, for example, a sensor that detects a triaxial angular velocity. The capacitance sensor 27 is a sensor that detects the capacitance on the touch panel 14. For example, the sub-processor 28 collects the acceleration of the mobile terminal 1 main body, which is the sensor result of the acceleration sensor 25. Furthermore, the sub processor 28 detects, for example, a non-contact proximity operation or a contact operation on the touch panel 14 using the hovering function based on the sensor result of the capacitance sensor 27. The hovering function is an operation function that detects an operation of the touch panel 14 by tracing in a non-contact state that is lightly separated from the touch panel 14. Furthermore, the sub processor 28 acquires the proximity coordinates at the time of detecting the proximity operation on the touch panel 14 and the contact coordinates at the time of detecting the contact operation based on the sensor result of the capacitance sensor 27. The coordinates are expressed by (x, y, z) of the horizontal x-axis and y-axis on the touch panel 14 and the vertical z-axis.

  The nonvolatile memory 29 is an area for storing various programs such as a coordinate determination program. The RAM 30 is an area for storing various information. The application CPU 31 controls the entire mobile terminal 1. The bus 32 connects various parts such as the application CPU 31 and the RAM 30 in the mobile terminal 1 to each other.

  FIG. 2 is an explanatory diagram illustrating an example of functional configurations of the sub processor 28 and the application CPU 31. The sub processor 28 and the application CPU 31 read out the coordinate determination program stored in the nonvolatile memory 29 and configure various processes as functions based on the read coordinate determination program. The sub processor 28 shown in FIG. 2 executes the proximity acquisition unit 28A, the contact acquisition unit 28B, and the acceleration detection unit 28C as functions. The application CPU 31 executes the first determination unit 31A, the second determination unit 31B, the third determination unit 31C, the fourth determination unit 31D, and the determination unit 31E as functions.

  When the hovering function is activated, the proximity acquisition unit 28A acquires the coordinates at the time of detecting the proximity operation as the proximity coordinates when the proximity operation on the touch panel 14 is detected through the capacitance sensor 27. The proximity acquisition unit 28A holds the acquired proximity coordinates and the detection time at the time of detection of the proximity operation in the RAM 30. When the contact operation on the touch panel 14 is detected through the capacitance sensor 27, the contact acquisition unit 28B acquires the coordinates at the time of detection of the contact operation as the contact coordinates, and holds the contact coordinates in the RAM 30. The acceleration detection unit 28C samples the acceleration through the acceleration sensor 25 from the timing when the proximity coordinates are acquired, and holds the acceleration sampling data in the RAM 30.

  3 is an explanatory diagram illustrating an example of the positional relationship between the proximity coordinates and the contact coordinates from the viewpoint of the side surface of the touch panel 14, and an explanatory diagram illustrating an example of the positional relationship between the proximity coordinates and the contact coordinates from the viewpoint of the plane of the touch panel 14 in FIG. . The horizontal direction of the plane of the touch panel 14 is expressed by the x axis and the y axis, and the vertical direction is expressed by the z axis. When the proximity acquisition unit 28A detects a proximity operation that is operated in a non-contact state where the operation finger F does not contact the surface of the touch panel 14 as shown in FIGS. 3A and 4A, the proximity acquisition unit 28A performs the proximity operation. The proximity coordinates (x1, y1, z1) at the time of detection are acquired. When the contact acquisition unit 28B detects a contact operation operated in a contact state in which the operation finger F is in contact with the surface of the touch panel 14 as illustrated in FIGS. 3B and 4B, the contact acquisition unit 28B detects the contact operation. The contact coordinates (x2, y2, z2) at the time are acquired.

  The first determination unit 31A determines whether or not a predetermined time has elapsed from the detection time when the proximity operation is detected. The predetermined time is, for example, 3 seconds. The first determination unit 31A has a hovering function from the proximity operation to the contact operation because it takes too much time from the proximity operation detection to the contact operation when a predetermined time has elapsed from the detection time of the proximity operation. It is determined that this is not an operation. 31 A of 1st determination parts continue the monitoring operation | movement waiting for detection of contact operation, when predetermined time has not passed from the detection time of proximity | contact operation.

  The second determination unit 31B calculates a coordinate movement direction from the proximity coordinates to the contact coordinates based on the proximity coordinates and the contact coordinates. For example, the second determination unit 31B calculates the movement amount (x2-x1) of the x-axis value and the y-axis value among the proximity coordinates (x1, y1, z1) and the contact coordinates (x2, y2, z2). The coordinate movement direction is calculated from the movement amount (y2−y1). Further, the second determination unit 31B compares the proximity coordinates (x1, y1) and the contact coordinates (x2, y2) with the values of the x-axis and the y-axis, and determines whether the proximity coordinates and the contact coordinates are different. judge. When the proximity coordinates and the contact coordinates are the same, that is, (x1 = x2) and (y1 = y2), the second determination unit 31B determines that the proximity operation and the contact operation are operations of the same coordinate. In the case where the proximity coordinates (x1, y1) and the contact coordinates (x2, y2) are different, that is, in the case of (x1 ≠ x2) and (y1 ≠ y2), the second determination unit 31B performs the proximity operation and the contact operation. Judged as an operation with different coordinates.

When the proximity coordinates and the contact coordinates are different, the third determination unit 31C reads acceleration sampling data from the proximity coordinates (x1, y1, z1) acquisition to the contact coordinates (x2, y2, z2) acquisition from the RAM 30, The terminal acceleration is calculated from the acceleration sampling data. Note that the terminal acceleration is the acceleration of the mobile terminal 1 generated until the operating finger reaches the contact coordinates from the proximity coordinates. The third determination unit 31C calculates the terminal acceleration using the square root of the sum of squares of the x-axis and y-axis values (x ² + y ² ) from the acceleration sampling data. Furthermore, the third determination unit 31C determines whether or not the calculated terminal acceleration is equal to or greater than a predetermined value. As a result, when the calculated terminal acceleration is equal to or greater than a predetermined value, the third determination unit 31C determines that an external force has been generated on the mobile terminal 1 itself so as to move from the proximity coordinates to the contact coordinates. Note that the predetermined value is an acceleration that moves to the contact coordinates from the proximity coordinates.

  The fourth determination unit 31D compares the terminal acceleration direction of the terminal acceleration with the coordinate movement direction, and the terminal acceleration direction is a predetermined direction with respect to the coordinate movement direction, for example, the same direction as the coordinate movement direction. It is determined whether or not. The fourth determination unit 31D includes the signs “+” and “−” of the x-axis and y-axis values in the terminal acceleration direction, and the signs “+” and “−” of the x-axis and y-axis values in the coordinate movement direction. And compare. FIG. 5 is an explanatory diagram illustrating an example of the relationship between the terminal acceleration direction and the coordinate movement direction. The signs of the x-axis and y-axis values in the terminal acceleration direction shown in FIG. 5 are “+”. Also, the signs of the x-axis and y-axis values in the coordinate movement direction are also “+”. That is, since the sign (+, +) of the terminal acceleration direction (+ x3, + y3) and the sign (+, +) of the coordinate movement direction (+ x4, + y4) match in the fourth determination unit 31D. It is determined that the terminal acceleration direction and the coordinate movement direction are the same direction. As a result, when the terminal acceleration direction and the coordinate movement direction are the same direction, the fourth determination unit 31D determines that the contact operation is due to an external force generated by the mobile terminal 1 itself that is not intended by the user.

  For example, the fourth determination unit 31D does not match the sign (+ x, + y) of the terminal acceleration direction (+ x3, + y3) and the sign (+ x, -y) of the coordinate movement direction (+ x4, -y4). In this case, it is determined that the terminal acceleration direction and the coordinate movement direction are not the same direction. As a result, if the terminal acceleration direction and the coordinate movement direction are not the same direction, the fourth determination unit 31D determines that the contact operation is not due to the generation of an external force of the mobile terminal 1 itself.

  When the fourth determination unit 31D determines that the terminal acceleration direction and the coordinate movement direction are the same direction, the determination unit 31E determines that the contact operation is caused by an external force generated by the mobile terminal 1 itself that is not intended by the user. The proximity coordinates before detection are determined as operation coordinates. As a result, the application CPU 31 executes an operation command corresponding to the proximity coordinates.

  The determination unit 31E determines that the contact operation is not due to the generation of an external force of the mobile terminal 1 when the acceleration direction and the coordinate movement direction are not the same in the fourth determination unit 31D, and operates the contact coordinates when the contact operation is detected. Determine as coordinates. As a result, the application CPU 31 executes an operation command corresponding to the contact coordinates.

  Next, the operation of the mobile terminal 1 of this embodiment will be described. FIG. 6 is a flowchart illustrating an example of processing operations of the sub processor 28 and the application CPU 31 on the portable terminal 1 side related to the coordinate determination process. The coordinate determination process shown in FIG. 6 acquires the contact coordinates after acquiring the proximity coordinates while using the hovering function. For example, when the terminal acceleration direction and the coordinate movement direction are the same direction, the proximity coordinates before detecting the contact operation are obtained. This is a process for determining operation coordinates.

  In FIG. 6, the application CPU 31 determines whether or not the hovering function is activated (step S11). The hovering function is activated by a setting operation on the touch panel 14, for example. When the application CPU 31 activates the hovering function (Yes at Step S11), the application CPU 31 determines whether or not a stop request for the hovering function is detected (Step S12). The stop request is made by a stop operation on the touch panel 14, for example.

  When the proximity acquisition unit 28A in the sub-processor 28 does not detect the hovering function stop request (No at Step S12), the proximity acquisition unit 28A determines whether the proximity operation on the touch panel 14 is detected through the capacitance sensor 27. (Step S13). When the proximity acquisition unit 28A acquires the proximity coordinates at the time when the proximity operation is detected on the touch panel 14 (Yes at Step S13), the proximity acquisition unit 28A acquires the proximity coordinates (x1, y1, z1) at the time when the proximity operation is detected (Step S14).

  After acquiring the proximity coordinates, the proximity acquisition unit 28A holds the acquired proximity coordinates and the detection time of the proximity operation in the RAM 30 (step S15). The acceleration detection unit 28C in the sub processor 28 holds the proximity coordinates and the detection time of the proximity operation in the RAM 30, and then samples the acceleration of the portable terminal 1 detected by the acceleration sensor 25 and sequentially holds it in the RAM 30 (step). S16).

  The contact acquisition unit 28B in the sub processor 28 determines whether or not a contact operation on the touch panel 14 has been detected (step S17). If the first determination unit 31A in the application CPU 31 does not detect the touch operation on the touch panel 14 (No at Step S17), the first determination unit 31A determines whether or not a predetermined time, for example, 3 seconds has elapsed since the proximity coordinate detection time. Determination is made (step S18).

  If a predetermined time has elapsed from the detection time of the proximity operation (Yes at Step S18), the first determination unit 31A proceeds to Step S12 to determine whether or not a stop request for the hovering function has been detected. If the predetermined time has not elapsed since the detection time of the proximity operation (No at Step S18), the first determination unit 31A proceeds to Step S16 in order to continue sampling of acceleration.

  When the contact acquisition unit 28B in the sub-processor 28 detects a contact operation on the touch panel 14 (Yes at Step S17), the contact acquisition unit 28B acquires the contact coordinates (x2, y2, z2) when the contact operation is detected on the touch panel 14 (Step S17). S19). Based on the acquired proximity coordinates and contact coordinates, the second determination unit 31B in the application CPU 31 calculates the coordinate movement direction using the movement amounts (x2-x1) and (y2-y1) of the x-axis and the y-axis (Step 2). S20).

  The second determination unit 31B in the application CPU 31 compares the x-axis and y-axis values of the proximity coordinates and the contact coordinates (step S21), and the proximity coordinates (x1, y1) and the contact coordinates (x2, y2) Are different from each other (step S22). When the proximity coordinate and the contact coordinate are different (Yes at Step S22), the second determination unit 31B acquires the acceleration sampled between the proximity coordinate acquisition and the contact coordinate acquisition from the RAM 30 (Step S23).

The third determination unit 31C in the application CPU 31 calculates the terminal acceleration using the square root of the sum of squares of the x-axis and y-axis values (x ² + y ² ) from the acceleration from the proximity coordinate acquisition to the contact coordinate acquisition (step S24). ). The third determination unit 31C determines whether or not the terminal acceleration is greater than or equal to a predetermined value (step S25). When the terminal acceleration is greater than or equal to a predetermined value (Yes at Step S25), the fourth determination unit 31D in the application CPU 31 determines the signs of the x-axis and y-axis values of the terminal acceleration and the x-axis and y-axis of the coordinate movement direction. The signs of the values are compared (step S26). The fourth determination unit 31D determines whether or not the sign of the terminal acceleration matches the sign of the coordinate movement direction (step S27).

  When the sign of the terminal acceleration matches the sign of the coordinate movement direction (Yes at step S27), that is, when the direction of the terminal acceleration is the same direction as the coordinate movement direction, the determination unit 31E in the application CPU 31 detects the contact operation. Are determined as operation coordinates (step S28). As a result, the mobile terminal 1 determines that the contact operation is due to an external force generated by the mobile terminal 1 itself that is not intended by the user, determines the proximity coordinates before detecting the contact operation as the operation coordinates, and performs an operation corresponding to the proximity coordinates. Execute a command. For example, as shown in FIG. 4B, in the case of the character input with the proximity coordinate “5” and the character input with the contact coordinate “6”, the application CPU 31 determines the proximity coordinate as the operation coordinate. The operation command for character input “5” corresponding to the coordinates is executed. Then, the application CPU 31 proceeds to step S12 in order to determine whether or not a stop request for the hovering function has been detected.

  When the proximity coordinate and the contact coordinate are not different (No at Step S22), the determination unit 31E determines the contact coordinate at the time of detecting the contact operation as the operation coordinate (Step S29). As a result, since the proximity coordinates and the contact coordinates are the same, the mobile terminal 1 determines the contact coordinates at the time of detecting the contact operation as the operation coordinates, and executes an operation command corresponding to the contact coordinates. As shown in FIG. 4B, the application CPU 31 executes a character input operation command of “6” corresponding to the contact coordinates in order to determine the contact coordinates as the operation coordinates. The application CPU 31 proceeds to step S12 in order to determine whether or not a hovering function stop request has been detected.

  If the terminal acceleration is not equal to or greater than the predetermined value (No at Step S25), the determination unit 31E proceeds to Step S29 in order to determine the contact coordinates at the time of detecting the contact operation as the operation coordinates. As a result, since the terminal acceleration is not equal to or greater than the predetermined value, the mobile terminal 1 determines the contact coordinates at the time of detecting the contact operation as the operation coordinates, and executes an operation command corresponding to the contact coordinates.

  When the sign of the terminal acceleration and the sign of the coordinate movement direction do not match (No at Step S27), the determination unit 31E proceeds to Step S29 in order to determine the contact coordinates at the time of detecting the contact operation as the operation coordinates. As a result, since the terminal acceleration direction and the coordinate movement direction are not the same direction, the mobile terminal 1 determines the contact coordinates at the time of detecting the contact operation as the operation coordinates, and executes an operation command corresponding to the contact coordinates.

  When the application CPU 31 detects a stop request for the hovering function (Yes at Step S12), the application CPU 31 stops the hovering function (Step S30), and ends the processing operation illustrated in FIG. When the proximity acquisition unit 28A does not detect the proximity operation (No at Step S13), the proximity acquisition unit 28A proceeds to Step S12 in order to determine whether or not a stop request for the hovering function is detected.

  The application CPU 31 that executes the coordinate determination process calculates the coordinate movement direction based on the proximity coordinates at the time of detecting the proximity operation and the contact coordinates at the time of detecting the contact operation. Furthermore, the application CPU 31 calculates the terminal acceleration from the acceleration from the proximity coordinate acquisition to the contact coordinate acquisition. Furthermore, the application CPU 31 differs from the proximity coordinates and the contact coordinates, the terminal acceleration is equal to or greater than a predetermined value, the sign of the x-axis and y-axis values of the terminal acceleration, and the x-axis and y-axis values of the coordinate movement direction. When the codes match, the proximity coordinates before detecting the touch operation are determined as the operation coordinates. As a result, the mobile terminal 1 determines that the contact operation is due to an external force generated by the mobile terminal 1 itself that is not intended by the user, determines the proximity coordinates before detecting the contact operation as the operation coordinates, and performs an operation corresponding to the proximity coordinates. Can execute commands.

  When the proximity coordinates and the contact coordinates are the same, the application CPU 31 determines the contact coordinates at the time of detecting the contact operation as the operation coordinates. As a result, the portable terminal 1 can execute the operation command corresponding to the contact coordinates at the time of detecting the contact operation because the proximity coordinates and the contact coordinates are the same coordinates.

  When the terminal acceleration is less than the predetermined value, the application CPU 31 determines the contact coordinates at the time of detecting the contact operation as the operation coordinates. As a result, since the terminal acceleration is less than the predetermined value, the mobile terminal 1 can execute an operation command corresponding to the contact coordinates at the time of detecting the contact operation.

  If the sign of the x-axis and y-axis values of the terminal acceleration does not match the sign of the x-axis and y-axis values of the coordinate movement direction, the application CPU 31 determines the contact coordinates at the time of detecting the touch operation as the operation coordinates. To do. As a result, since the terminal acceleration direction and the coordinate movement direction are not the same direction, the mobile terminal 1 can execute an operation command corresponding to the contact coordinates at the time of detecting the contact operation.

  When the mobile terminal 1 of this embodiment detects a contact operation after detecting the proximity operation, the proximity coordinate is different from the contact coordinate, the terminal acceleration is equal to or greater than a predetermined value, and the terminal acceleration direction is the same as the coordinate movement direction. The previous proximity coordinate is determined as the operation coordinate. As a result, the mobile terminal 1 can select the operation coordinates intended by the user even when movement due to the external force of the mobile terminal 1 itself that is not intended by the user occurs immediately before the contact operation, and thus it is possible to suppress erroneous input.

  For example, the mobile terminal 1 can reliably prevent erroneous input of characters even when characters are input using the hovering function in a situation where shaking occurs in a vehicle or the like. That is, even when the movement from the proximity coordinates to the contact coordinates occurs due to the shaking of the mobile terminal 1 itself, it can be determined that the user has not intentionally moved from the proximity coordinates to the contact coordinates, so that erroneous input of characters is ensured. Can be prevented.

  In the above embodiment, when the proximity coordinate and the contact coordinate are different, the terminal acceleration is equal to or greater than a predetermined value, and the terminal acceleration direction is the same as the coordinate movement direction, the proximity coordinate is determined as the operation coordinate. However, when the proximity coordinate and the contact coordinate are different and the terminal acceleration direction is the same as the coordinate movement direction, the proximity coordinate may be determined as the operation coordinate. As a result, the mobile terminal 1 can select the operation coordinates intended by the user even when movement by the external force of the mobile terminal 1 itself unintended by the user occurs immediately before the contact operation.

  In the above embodiment, it is determined whether or not the detection time at which the first determination unit 31A detects the proximity operation has passed a predetermined time, for example, 3 seconds, but the predetermined time is limited to 3 seconds. Instead, it can be changed as appropriate. Further, although it is determined whether or not the detection time has passed a predetermined time, it may be the time when the proximity coordinates are acquired instead of the detection time.

  Based on whether the signs of the x-axis and y-axis values in the terminal acceleration direction and the signs of the x-axis and y-axis values in the coordinate movement direction are the same in the fourth determination unit 31D, the terminal acceleration direction is determined. It was determined whether or not the direction was the same as the coordinate movement direction. However, the present invention is not limited to the code comparison and can be changed as appropriate.

  When the terminal acceleration direction is the same as the coordinate movement direction, the application CPU 31 determines the proximity coordinate as the operation coordinate. However, the application CPU 31 does not limit the terminal acceleration direction to the same direction as the coordinate movement direction. For example, when the terminal acceleration direction is opposite to the coordinate movement direction, the application CPU 31 determines the proximity coordinate as the operation coordinate. Anyway.

  In addition, each component of each part illustrated does not necessarily need to be physically configured as illustrated. In other words, the specific form of distribution / integration of each part is not limited to the one shown in the figure, and all or a part thereof may be functionally or physically distributed / integrated in arbitrary units according to various loads and usage conditions. Can be configured.

  Furthermore, various processing functions performed in each device are performed on a CPU (Central Processing Unit) (or a microcomputer such as an MPU (Micro Processing Unit), MCU (Micro Controller Unit), etc.) in whole or in part. You may make it perform. Various processing functions may be executed entirely or arbitrarily on a program that is analyzed and executed by a CPU (or a microcomputer such as an MPU or MCU) or hardware based on wired logic. Needless to say.

  By the way, the various processes described in the present embodiment can be realized by causing a program prepared in advance to be executed by a processor such as a CPU in the terminal device. Therefore, in the following, an example of an electronic device that executes a program having the same function as in the above embodiment will be described. FIG. 7 is an explanatory diagram illustrating an example of an electronic device that executes the coordinate determination program.

  The electronic device 100 that executes the coordinate determination program illustrated in FIG. 7 includes a touch panel 110, a first detection unit 120, a second detection unit 130, a ROM 140, a RAM 150, and a CPU 160. Furthermore, the touch panel 110, the first detection unit 120, the second detection unit 130, the ROM 140, the RAM 150, and the CPU 160 are connected via a bus 170. The first detection unit 120 detects a non-contact state proximity operation or a contact state contact operation on the touch panel 110. The second detection unit 130 detects the acceleration of the electronic device 100 main body.

  The ROM 140 stores in advance a coordinate determination program that exhibits the same function as in the above embodiment. The ROM 140 stores an acquisition program 140A, a determination program 140B, and a determination program 140C as coordinate determination programs. The coordinate determination program may be recorded on a computer-readable recording medium instead of the ROM 140. The recording medium may be, for example, a portable recording medium such as a CD-ROM, a DVD disk, or a USB memory, or a semiconductor memory such as a flash memory.

  The CPU 160 reads the acquisition program 140A from the ROM 140, and functions on the RAM 150 as the acquisition process 150A. Further, the CPU 160 reads the determination program 140B from the ROM 140, and functions on the RAM 150 as the determination process 150B. Further, the CPU 160 reads the determination program 140C from the ROM 140, and functions on the RAM 150 as the determination process 150C.

  CPU160 acquires the contact coordinate at the time of contact operation, after acquiring the proximity coordinate at the time of proximity operation on the touch panel 110. FIG. When the proximity coordinate and the contact coordinate are different, the CPU 160 determines that the acceleration direction of the electronic device 100 obtained from the acceleration of the electronic device 100 body from the proximity coordinate acquisition to the contact coordinate acquisition is changed from the proximity coordinate to the contact coordinate. It is determined whether the direction is a predetermined direction with respect to the moving direction. When the acceleration direction of the main body of the electronic device 100 is a predetermined direction, the CPU 160 determines the proximity coordinates as operation coordinates for executing the operation command. As a result, even when the movement of the electronic device unintended by the user occurs immediately before the contact operation, the operation coordinates intended by the user can be selected.
